Barbour headlined a fundraising luncheon for LePage at DiMillo’s Floating Restaurant in Portland on Monday. WCSH-TV quotes Barbour as saying LePage has been successful in the polls because he has attracted support from Republicans, Democrats and independent voters, especially tea party voters.

Barbour is past chairman of the Republican National Committee and current chairman of the Republican Governors’ Association. He’s in his second term as Mississippi’s governor.

The visit comes after former President Bill Clinton campaigned on behalf of Democrat Libby Mitchell.
